The cast of MTV's Teen Mom 2 is pretty consistent in making bad relationship decisions. That's just a fact. And Monday night's episode was no exception. In fact, the entire episode was basically one gigantic glimpse into the world of these girls' relationships. It was pretty scary.

First up, we have the good news. Chelsea is finally (FINALLY!) seeking help for her incredibly low self-esteem and problems with Adam. Seeing a shrink may be the best thing to ever happen to that girl. Let's hope things change for her.

Then the bad news: Jenelle has a new man named Josh (massive eye-roll). We all know how her various whims with men end up, and though this guy seems like a "keeper," we know he's not since she's not with him. Jenelle has SUPER high standards, too. "At least you have a steady job." Yeah. Way to aim high.

Meanwhile Kailyn is losing her mind over the breakup with Jordan and talking to Jo about it. Does this seem smart? Maybe not. But she's doing it anyway!

Here's a lesson (much as I love Kailyn): When the guy who you cheated on your boyfriend with, who ALSO happens to be your baby daddy that jerked you around after you cheated, is the person you turn to for relationship advice, maybe it's time to make a girlfriend or two. Just a thought.

Of course, the best moment of the night came when Corey Simms' parents offered him the sage relationship advice to "avoid skinny minnies" and go for a less pretty girl so she would be less apt to cheat.

I am not sure how to say this, so let me be clear: WORST. RELATIONSHIP. ADVICE. EVER. Seriously, people. What the hell?

Corey's mom laughed and said he just needs a girl with "morals" (ooooh burn), but his dad was serious. Make an ugly woman your wife. Wasn't that a song?

Corey and Leah's problems didn't happen because she was too thin. Or too pretty. Corey's parents implying he can only get an ugly girl is insulting to him, true. But it's also insulting to all women in general. Really? Only ugly women can be faithful?

Is it any wonder these people can't be happy in relationships? With two daughters, I sure as hell hope Corey rethinks his parents' statement. And I hope he gets some better parenting advice than he does relationship advice. Nice.
